Cansina – Web Content Discovery Tool

Cansina is a Web Content Discovery Application. It is well known Web applications don’t publish all their resources or public links, so the only way to discover these resources is requesting for them and check the response. Cansina duty is to help you making requests and filtering the responses to tell apart if it is an existing resource or just an annoying or disguised 404. Other kind of useful responses (401, 403, …) are processed in a similar fashion. Responses are kept in a sqlite database for later process or viewing.

You can stop and resume a task by ctrl-c, a resume file will be generated for you.

Usagecansina.py -h for a comprehensive list of features and choicesSimple case

cansina.py -u target_url -p payload_filename

Will make GET requests using 4 threads by default

Banning HTTP responde codes to output

cansina.py -u target_url -p payload_filename -b 404,400,500

Selected codes will be skipped

Adding a .php extension to every record in payload

cansina.py -u target_url -p payload_filename -e php

Make all payload entries end with an extension

Adding a list of extensions

cansina.py -u target_url -p payload_filename -e php,asp,aspx

Same as above but will repeat every request for every extension provided

Inspecting content

cansina.py -u target_url -p payload_filename -c look_for_this_text

Cansina will report to screen if the content is detected in response

Filtering by content

cansina.py -u target_url -p payload_filename -d look_for_this_text

If the content is found it will be processed as a 404 Not Found page

Autodiscriminator

cansina.py -u target_url -p payload_filename -D

First, Cansina will try to make and remember a 404 response and will skip similar responses

Replacing

cansina.py -u target_url/

*

_this/ -p payload_filename

Simple string replacing. Useful when a URL pattern is observable

Size filtering

cansina.py -u target_url -s 1495 -p payload_filename

If you don’t want a response and know its size is fixed this could help skipping all those responses.Also, it can be a list of sizes:

cansina.py -u target_url -s 0,1495,1337 -p payload_filename

Uppercase all requests

cansina.py -u target_url -U -p payload_filename

Just make every payload UPPERCASE

Threading

cansina.py -u target_url -t8 -p payload_filename

Set the threading level. 4 by default.

Change GET -> HEAD requests

cansina.py -u target_url -H -p payload_filename

Make requests using HEAD HTTP method. Be aware size and content filtering won’t work

Delay between requests

cansina.py -u target_url -T 1.25 -p payload_filename

Set a delay between resquests. Time is set in float format. E.g: 1.25 seconds

User agent

cansina.py -u target_url -p payload_filename -a user_agent

Set an alternative User-Agent string

Proxy requests

cansina.py -u target_url -p payload_filename -Phttp://127.0.0.1:8080

Simple http proxy

Basic authentication

cansina.py -u target_url -p payload_filename -Auser:password

Manages basic authentication

Resume session

cansina.py -r resume_file

Resume last interrupted session with all options and payload with former linenumber

Parse robots.txt

cansina.py -R

Cansina will parse the robots.txt file an use it as a payload if it exists
